Steve,

I always just buy a couple of gallons and with a couple of 
empty containers, I make up 50-50 mix.

There is a plug you can remove on each side of the block to 
drain it, but it really isn't necessary.

I usually drain the radiator, and run fresh water in the 
system till it runs clear (motor running, keep the radiator 
full).

Then let everything drain out that you can.  Put in about 
1/2 a gallon of straight anti-freeze and then top off with 
50-50 mix.  Check the cooling freeze number after driving a 
few miles, but it should be just fine.
